it worked and showed me the Line witch was written in my file but now my problem is how am gonna use that line as a path i mean for example if am gonna execute a linux command on that file like dpkg -i /path/to/the/file how am gonna export it from The $Line variable and use it after the command.
how to program in bash, an i have a problem, i am trying compare values in between 2 values (from another file), so far my solution is to make a nested for loop, but that causes it to compare every value. Here is a visulization of what i want
file.a 2,3,4,5 file.b 3 5
i want the values 2, 3, 4, 5 from file.a to be compared inbetween values 3 5, 6 9,1 2, 4 7 from file.b (var1 is the value im comparing, var2 is the less value, var 3 is the greater value)
for i in $var1 do for k in $var2 do
my problem with the above code is it compares EVERYINNG, not the values inbetween what i want (which is 3 5, 6 9 etc).
I have a text file which stores the list of files & dir, I want to get only file's extensions from this file & want to store it in another file.eg, below is the file's contents & from it I want to get the extensions sh, pl & h & want to store it in another file. Also I don't want directory list.
A scripts/services_restarter.sh A scripts/svn post_commit scripts A scripts/tmp/
write such script (bash script). I have some text file with name filename.txt I must check if this file contains string "test-string-first", I must cut from this file string which follows string "keyword-string:" and till first white-space and save it to some variable.
For example. File: PHP Code: PHP Code: Start 15022011 Eng 12-3-42 SN1232324422 11 test-string-first SN322211 securities HH keyword-string:123456321-net mark (11-22)
I have a script which checks on my jobs that run on some cluster.The script, "script.sh", takes as an input the job-id for the job to be checked. Sometimes I have 100s of jobs and I want to check them all (for successful completion.) I could put these job-ids into a text file, "job-id.txt", each id in its own line.For each job-id, the script would ask me few questions (with a yes or no answers) to see if I want to do some other checks for each job-id.I want to know how may I direct my job-ids from this text file into the script one job-id at a time.
I am trying to think of a logic where my file contains some data I had to read and do some processing. Issue is that file contains data multiple times. For example:
::::::::::: var1=value1 var2=value2
I have to read first paragraph of variables and do some processing and then move on until the end of file. Variable names are same in whole file but for each paragraph the value is different. I can't think of a logic to attain this task. How can I do it? It should be a simple bash script, but I am not able to work out.
Now in my bash script, I want to get the output /home/user instead of $HOME once read. So far, I have managed to get the $HOME variable but I can't get it to echo the variable. All I get is the output $HOME.
i am on processing text tasks And i found that if you assign a text to a variable is chomp'ed automatically the newline
The problem is i can only access the items/lines using:
for line in $variable do echo $line # Other commands done
how do i convert this to an indexed array. More importantly, how do i get access to individual $line, ..., $line[n] Another thing, if the file.txt, has lines with spaces it is a mess using the for...in..., but echoing prints line by line...o_0
I've been reading about getopt and getopts but it doesn't seem like it's possible to parse arguments like --foo or even -foo. I've started my own script trying to achieve this, but I'm still wondering if I'm losing performance and if there is a better way to do this task.
Also I'm using the [[ =~ ]] regex syntax which seems to be available only in newer bash versions, should it be a big issue? My bash version: GNU bash, version 4.1.7(2)-release (x86_64-unknown-linux-gnu)
Here the description of the issue I am having.I am writing a bash test script which reads lines from a file, builds ISO messages, sends them to a server, reads the response with response code and reports the result of the test to a file or on the screen.The message that I need to send is 94 characters long.Here's the portion of a code that I initially wrote:
~ Open socket. exec 3<>/dev/tcp/172.26.0.25/9991 #~ Send msg.
bash 3.1.17(2) I'm trying do write a shell script which must operate on each line of an ASCII text file. So, all the code must be inside a loop, and inside the loop, the first thing should be to read the next line from the file. I have the bash read command. But it reads from stdin. Any way to make read from a file?
I'm writing a bash script where I read a text file (containing a column of numbers) and store each line in an array. There seem to be some problems with the whole thing however, but only for some files and not others. Here's what I do:
Code: #!/bin/bash file=time_notOk.txt ### The file with a column of numbers i=0 ### Array counter ### Read the file
I need to insert 3-4 lines of text to the beginning of a text file. The file is a largish MYSQL dump, the result of a backup shell script. This shell script should insert the required text.I've wrestled with sed, but lost.
I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.
I want to display something in my text view widget in glade using c code. that's all right. now I need to attach a save button beneath the text view.so that on click the text view content should save as a txt file..
So, while displaying the contents of above file on a web page, I want to format the field names found in the log file: User Name:, Reported Problems Description:, and Remarks:. These fields may contain a variable length of text and no specific line number is assumed for them to appear on.
